    Parents! Learn more about your child’s health by joining the Shape Up! Keiki Study

    The Shape Up! Keiki research study can help you and your kids learn about their health while helping researchers build new technologies to understand the human body.

    Your child’s participation will help us find quick and accessible ways to measure health using body shape. This will help scientists understand how body shape is related to factors like physical strength and heart health.

    Walkthrough of the Lab

    Please take a moment to watch this video for a brief tour of our lab and the procedure for this study.


    Learn more about our procedure by visiting our scans & tests page or read the below FAQ for information specific to our younger participants.

    What does it cost?

    FREE! After the visit, kids and their parents receive copies of their health information at no cost. For each participant in the study, you also receive a gift card for your time.

    What is the Questionnaire?

    We will ask the child’s parent to fill out a questionnaire during the visit. The questionnaire takes about 15 minutes to complete and does not have to be completed in one sitting. The questions will cover your child’s diet and development. To learn more about your child’s diet, we will ask you to complete an Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24) where your child’s food record from the past 24 hours can be entered. To learn more about your child’s social-emotional development we will ask you to complete the Ages and Stages questionnaire.

    Why are you taking Urine and/or Saliva Samples?

    For urine and saliva, we use a method called the deuterium dilution method. Your child will be asked to drink deuterium-enriched water, which researchers also call “heavy water.” This is completely safe and is simply water that can be measured. Throughout the visit, we will collect urine and saliva samples and measure the amount of heavy water in them, which allows us to calculate body composition.

    Saliva samples are taken gently using a soft swab.

    Is it safe for my child to have a DXA Scan?

    Visit our DXA Scan page to read more about what it is and what it measures.

    DXA Scans are safe and reliable for all ages. The amount of radiation used for this procedure is small, much less than a person would receive from a chest or dental x-ray. The radiation dose for a DXA scan is about the same as the radiation your child is naturally exposed to in the environment in less than one day.

    A researcher or technician will be present in the room at all the times. For infants, we have safety measures to keep them secure on the scanning table.

    DXA scans are safe and children are welcome to watch videos during the scan.

    How do you measure babies too young to stand on their own?

    Our Shape Up! Keiki study includes all ages below 5 years old, so it’s important to us to make sure any age is comfortable and safe. For many of our scans, we have special procedures for infants.

    For a DXA Scan, we typically wait until the time of day when your baby is most relaxed and may swaddle them to keep them still.

    Babies are swaddled and can relax while the scan takes place.

    For the Bodpod, we have a special version called the Peapod as well as inserts and seats to support younger children. This tool allows us to take the same measurements with your baby laying down.

    Lastly, 3D optical scans can still be done using a clear crib. This allows a full body scan to be taken without the need for standing and keeps your child safely in place.

    This crib allows babies to lay normally while cameras create a full body scan.

    How long is a visit?

    The time can vary depending on the participant. This will be a one day visit where we move through each scan and test at a pace that works best for your child. We allow time for breaks between procedures and ensure all participants are comfortable before starting a scan. Most of the measurements will be completed in the first couple of hours and the rest of the time will be for a few last tests, such as urine tests. In total, we estimate the visit taking around 5 hours.
